摘要:
A liquid ejecting head is constituted by a substrate to which elements for generating energy utilized for ejecting liquid and a supply port for supplying the liquid to be ejected are provided; a plurality of ejection outlets, for ejecting the liquid, provided corresponding to the elements; pressure chambers each communicating with an associated ejection outlet; and flow paths communicating between the pressure chambers and the supply port. The flow paths include at least one pair of flow paths connected to an associated pressure chamber in a symmetrical manner and include flow paths overlapping with each other with respect to a direction from an associated ejection outlet toward the substrate.
